Schaller M6 180 Guitar Tuning Machine
The Schaller M6 180 tuning machine delivers exceptional tuning accuracy and stability with an advanced 1:18 gear ratio. Designed for smooth, velvety operation, each unit features high-precision CNC-machined components and a self-locking drive mechanism that ensures reliable performance without slip or backlash.
Engineered with premium brass string posts and permanently lubricated with Schaller special grease, these sealed tuners are completely maintenance-free. The innovative stepped M6 flanged washer centers the string post securely through the hollow screw, eliminating tilting torque and protecting both the post and mounting screws without requiring stepped headstock drilling.
Crafted to directly replace previous M6 models without headstock modification, this tuning machine combines legendary design with modern engineering. It is available in various post configurations, button styles, and premium finishes to fit a wide range of electric and acoustic guitars.
